Rails - Apr 2005 - Problems with MissingSourceFile in <controller not set>#<action not set> in todo tutorial

Hello All,

I''ve just been playing with the Rails "ToDo" tutorial (at
http://darkhost.mine.nu:81/~vince/rails/tutorial.html ), and I have ben
thrown this error:
 MissingSourceFile in <controller not set>#<action not set>

I realise - by using the latest gem install for rails - that I am not
matching the tutorial instructions, but all the same, I''ve noted a
departure from previous naming conventions.

When I go to generate the model ToDo - a model gets created to_do.rb
instead of what is expected (by the tutorial) of todo.rb, giving the
above error.
If I copy to_do.rb to todo.rb it nows finds the model its looking for,
but I end up with other problems, further along, with the table names
being translated to to_do etc.

Can someone put me straight on this?

Thanks,

Piers Harding.

I haven''t looked at the tutorial for a while; however, I suspect
you''re mixing up the case on the model/controller name.  When Rails
encounters camel case words it splits them up with an underscore.
Thus ''./script/generate model ToDo'' will generate
app/models/to_do.rb
and ''./script/generate model Todo'' will generate
app/models/todo.rb.
You can''t generate ToDo, rename the file todo.rb and expect it to
work.  There are lots of places where active record will munge the
class name ToDo into to_do.

Hi Doug - thanks for the reply - the tutorial went like this:
$ ruby script/generate model Todo
$ ruby script/generate controller todo

So that would tie up with what you are saying.

I''ve tried changing all the generate steps to lowercased names, and so
far so good.

Thanks,

Piers Harding.

...that reminds me...

I''ve seen someone elsewhere mention that you should generate all your
controllers with lowercase names. I don''t recall seeing that anywhere
in the documentation, so I''m not sure if it''s a requirement or
not.
I''ve been using camel case for both model and controller without
issue, but are there hidden traps that I should be aware of?
